Uzara + Nifurtimox

Nifurtimox brand name: Lampit.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Uzara and Nifurtimox in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Nifurtimox states a food rule worth keeping to.

Uzara and Nifurtimox

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Nifurtimox and Uzara in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Nifurtimox

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nifurtimox is filed under a single classification — oral drugs. Uzara has documented interactions with 6 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (moderate) and macrolide antibiotics (moderate) — and none of Nifurtimox’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Uzara Itself Has Been Linked To

This is not an interaction — nothing below involves Nifurtimox. It is the side-effect record for Uzara on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Uzara, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • An irregular heartbeat / Raised blood pressure Worth acting on Additional detail

    “Orally, uzara can cause cardiotoxic effects, especially in patients with pre-existing cardiovascular disease. In one case report, a 68-year-old female with diabetes and hypertension was admitted to the emergency room with reduced left-ventricular function, pulmonary edema, and arrhythmia.”

Everything above comes from the Natural Medicines adverse-effect record for Uzara — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Nifurtimox’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Nifurtimox column appears here.

How to take them

Some Nifurtimox Products Have a Food Rule — Uzara Should Not Break It

At least one FDA label for a product containing Nifurtimox says to take it with food. If you take Uzara on an empty stomach out of habit, keep them separate — and take Nifurtimox with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Nifurtimox products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

LAMPIT tablets must be taken with food ( 2.1 ) Dosage of LAMPIT in Pediatric Patients (birth a to less than 18 years of age) (2.2) Body Weight Group Total Daily Dose of nifurtimox (mg/kg) 41 kg or greater 8 to 10 Less than 41 kg 10 to 20 a Term newborn with body weight greater than or equal to 2.5 kg • Administer LAMPIT tablets orally, three times daily with food for

From the Dosage and Administration section of the FDA label we read for Nifurtimox — where that label names a specific product, the instruction is that product's. See the Nifurtimox drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Everything else you take

See Every Supplement That Interacts With Nifurtimox

This page covers Uzara only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nifurtimox page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Nifurtimox page

“Nifurtimox (Lampit) treats Chagas disease over a course lasting weeks, and it only works if enough of each dose is absorbed, which is why the 17 supplements flagged here call for real vigilance. Every single one can change how oral medications are taken up from the gut.”

About Uzara

What is Uzara?

  • Diarrhea
  • Stomach cramps
  • Menstrual cramps (dysmenorrhea)
  • Headaches
  • Digestive upset

Uzara is a traditional African root remedy used mainly for diarrhea and stomach cramps. Because it contains cardiac glycosides that can affect the heart, it should be used cautiously and for short periods only. Talk to a pharmacist or doctor before using it, especially if you have heart problems, are pregnant, or take heart medications.

Xysmalobium undulatum · Apocynaceae · Dried root · Liquid extract, tincture, tablets, drops

An interaction check asks whether these two react with each other — it does not ask whether Uzara is a good idea for someone in your situation. Here is what our Uzara record says about it on its own.

Uzara: dosing

There is no well-established standard dose for Uzara, and products vary in strength. The right amount depends on the specific preparation, such as drops, tincture, or tablets.The safest approach is to follow the directions on the product label and use it only for short periods. Do not exceed the recommended amount, since higher doses raise the risk of heart-related side effects.

Taking Uzara and Nifurtimox Together: Common Questions

Is it safe to take Uzara with Nifurtimox?
We do not list a known interaction between Uzara and Nifurtimox. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Uzara and Nifurtimox at the same time of day?
At least one FDA label for a product containing Nifurtimox says to take it with food. If you take Uzara on an empty stomach out of habit, keep them separate and take Nifurtimox with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Nifurtimox products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Uzara and Nifurtimox combination checked?
Interactions in our licensed database are recorded against drug classes. Nifurtimox is filed under 1 classification, and Uzara has documented interactions with 6 drug classes — none of Nifurtimox's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Uzara interact with any other medications?
Yes. Uzara has 133 documented drug interactions in our database — Nifurtimox is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Nifurtimox interact with any supplements?
Yes. Nifurtimox has documented interactions with 17 supplements in our database — Uzara is not one of them. The Nifurtimox interaction page linked on this page lists every one, ranked by severity.
